Abstract

The invention discloses an electrocardiosignal processing method and device, a storage medium and a processor. The method includes the steps that a first electrocardiosignal in a first preset time period is obtained, wherein the first electrocardiosignal is used for characterizing electrocardiosignal changes between ventricle depolarization and repolarization; an offset sequence of the first electrocardiosignal is obtained, wherein multiple offset values contained in the offset sequence are used for characterizing changes of the first electrocardiosignal relative to reference voltage, and thereference voltage is extracted from an electrocardiosignal; the characteristics of the offset sequence of the first electrocardiosignal are extracted, and a characteristic vector is obtained, whereinthe characteristic vector comprises characteristics based on the poincare section, morphological characteristics and global characteristics; the characteristic vector is identified, and the offset type of the first electrocardiosignal is obtained. By means of the electrocardiosignal processing method and device, the storage medium and the processor, the technical problem that as a processing method for electric signals in an existing technical center is largely influenced by individual specificity and lead specificity, the processing efficiency is low is solved.

Description

technical field [0001] The invention relates to the field of electrocardiograms, in particular to a method and device for processing electrocardiogram signals, a storage medium, and a processor. Background technique [0002] An electrocardiogram (ECG) is a transthoracic recording of the electrophysiological activity of the heart in units of time, showing potential changes between different parts of the skin where electrodes are placed due to heart activity. ECG signals are usually composed of P waves, QRS structures, and T waves, reflecting the process of depolarization and repolarization of various parts of the heart. The ST segment refers to the ECG change between ventricular depolarization and repolarization, which is normally the isoelectric phase. When myocardial ischemia occurs, due to the potential difference between ischemic and non-ischemic cells, the damaging current is caused, and the ST segment of the ECG signal changes, which is higher or lower than the baselin...
